Daiso or The Daisō (ザ・ダイソー?) is the largest franchise of 100-yen shops in Japan.Daiso has a range of over 100,000 goods, of which over 40 percent are imported goods, many of them from China. Many of these are own-brand goods.

Daiso sets itself apart from other 100 yen shops by choosing not to sell closeout or factory second merchandise. Instead, they keep prices low by purchasing directly from manufacturers in very high volume, a strategy often compared to Wal-mart.
